Title: Process and catalyst for the catalytic conversion of hydrocarbons
IPC: B01J21/08
Filed: 1939-10-27
Abstract: 544,336. Cracking oil; catalysts. MOND, A. L. (Universal Oil Products Co.). Oct. 27, 1939; No. 28868. [Classes I (i) and 32] [Also in Group IV] A process for converting hydrocarbon oils of higher than gasoline end boiling point into antiknock motor fuel consists in subjecting such oils to contact with a catalyst comprising hydrated silica and hydrated zirconia substantially free from alkali at a temperature range of 425‹-650‹C. The catalyst may be prepared by several alternative methods as follows : (1) The hydrated silica washed free from alkali is precipitated and the zirconia deposited on the hydrated silica by suspending in a solution of a zirconium salt and basic precipitant. such as ammonium hydroxide, carbonate hydrosulphide or sulphide. The preferred zirconium salt is zirconyl chloride. (2) The hydrated silica gel may be admixed in the wet condition with hydrated zirconia, any alkali present being removed by washing. (3) Hydrated silica and hydrated zirconia may be co-precipitated simultaneously. The mixed hydrated silicahydrated zirconia mass prepared as above is calcined at temperatures from 540‹C.-820‹C. for a few hours. This treatment produces a product which still contains 2-5 per cent. of water. It is used as pellets or granules of 0.8 to 4 mesh per cm. size in examples (1) a catalyst is prepared by suspending pure hydrated silica in an aqueous solution of zirconyl chloride and adding ammonium hydroxide. The product is washed and heated to 150‹C. to dry, powdered and calcined at about 500‹C. (2) Commercial waterglass and zirconium nitrate aqueous solutions are mixed slowly, the zirconium nitrate being added to the water glass. When the addition is complete the mixed hydrated zirconia and hydrated silica will have precipitated. This is washed free from alkali dried, and calcined as in example (1). (3) A hydrated percipitated silica get is suspended in water and zirconium nitrate added. Ammonium hydroxide is added and the product worked up as before.

Title: Improvements in or relating to the production of anthraquinone derivatives
IPC: C07C225/34
Filed: 1931-10-22
Abstract: Halogenaminoanthraquinones.--2 - Chloro - 1 - arylsulphonamidoanthraquinones are prepared by reacting 1 : 2-dichloranthraquinone with an arylsulphonamide in a medium in which the 2-chloro-1-arylsulphonamidoanthraquinone is substantially insoluble at the temperature of reaction, in the presence of an acid absorber and a copper catalyst above about 170 DEG  C.  High yields are obtained and the arylsulphonyl group can be split off from the products by hydrolysis, for example, with sulphuric acid, to give 1-amino-2-chloranthraquinone.  In examples, 1 : 2-dichloroanthraquinone is heated with o- or p-toluenesulphonamide, potassium carbonate, copper acetate and cuprous choride in o-dichlorbenzene at 174-178 DEG .  The resulting products are hydrolysed by heating with concentrated sulphonic acid at 100 DEG C., and the solutions diluted at 80 DEG  C. to 80 per cent sulphuric acid, which is filtered prior to pouring into an excess water to give 1-amino-2-chloranthraquinone.

Title: Method and apparatus for bending glass sheets
IPC: C03B23/027
Filed: 1956-09-26
Abstract: 818,247. Glass manufacture. LIBBEYOWENS-FORD GLASS CO. Sept. 26, 1956 [Oct. 7, 1955], No. 29331/56. Class 56. In the bending of glass sheets, more particularly intended for parts of a vehicle body, the sheet is supported above the shaping mould, is heated and one end is twisted out of the original plane of support, the twisted sheet then being deposited on the shaping surface of the mould. As shown, the twisting is effected by arranging the pivot line 54 of the end part 22 of the mould on a skew with reference to the main part 21 of the mould. The glass, two sheets 23 being shown in Fig. 4, rests when flat upon a straight-edged member 43 at the upper end of the mould part 22, and marginally upon blocks 58, and at the lower end, upon the end bar 30 of the mould part 21 and against locating stops 33. Heat shields 36, 45 are positioned within the side members of the parts 21, 22 which members from the moulding surfaces. The shield 45 is stepped to attain continuity of surface with the shield 36 when the mould is in its shaping position. The blocks 58 are retracted by linkage as the mould closes to allow the glass sheets to sag onto the mould, the swinging of the mould part 22 producing, because of the skewed pivot, a lifting of one side of the glass above the other side and thus produces a twist in that end of the glass sheet ; or sheets, whilst it is sagging on to the closing mould parts. The sagging and twisting lifts the glass from the straight-edged member 43 so that it is not marked thereby.

Title: Improvements in or relating to power lifts for tractors
IPC: A01B63/111
Filed: 1947-11-14
Abstract: 684,150. Agricultural implements. FERGUSON, Inc., H. Nov. 14, 1947 [Nov. 25, 1946]. No. 30272/47. Class 6 (i). [Also in Group XXX]. The power lift of a tractor may alternatively be controlled by means which keep the traction exerted by the soil on an implement carried by the power lift constant, or by " follow up " means such that the position of the load always corresponds with the position of a manual control member. The tractor illustrated is equipped with the power lift described in Specification 470,069. Instead, however, of connecting at pivot 39A a member imparting a movement proportional to the draft load to the spring-urged sliding rod 36, a member is connected which imparts to the rod a movement proportional to that of the draft links 28 so that the position of the latter, when the system is in equilibrium, is determined by the position of the control quadrant 31. As shown, this movement is derived from a suitably shaped cam member 43, pivoted at 39A to the pivoted bracket 39 so that it rests against the differential housing, and operated by a roller 42 carried by an upper forked link 44 pivoted to the housing at 40 and constrained by struts 46 to move with the draft links 28. The roller 42 is mounted to slide on the link 44 so that it may be retracted from engagement with the member 43, being locked in position by a toggle linkage adapted to break in one direction only. In an alternative construction, the movement of the rod 36 is derived from a suitably-proportioned linkage of Z- configuration comprising a turnbuckle link extending rearwardly from the pivot 39A and pivoted to the upper end of a lever pivoted between its ends on the link 44 and pivoted at its lower end to the forward end of a further link pivoted at 47A. The power lift may operate a crane comprising a boom 62 reinforced by members 63 and supported by a saddle 64 from a pivot 65 at the upper ends of struts 66, 67 pivoted at 47A and 45 respectively. The rear end of the boom 62 is pivoted to a yoke 71A on a turnbuckle 68 pivoted at 52 to the link 44. It is stated that the linkage 66, 67, 49, 62 may be so proportioned that the load hook 76 travels in a straight vertical line with a speed proportional to that of the draft links 28. The hook 76 is shallow so that if the tractor tips, engagement of the load with the ground causes it to fall off the hook.
